We’re always up for a good little thriller or a piece of noir, and while buzz on “I, Anna” has pretty much been muted at this point despite premiering at the Berlin Film Festival earlier this month, the cast and material is compelling enough that we’re eager to give this one a shot.

Based on the book by Elsa Lewis, starring Gabriel Byrne, Charlotte Rampling, Hayley Atwell, Eddie Marsan and more, and written and directed by Barnaby Southcombe, if anything, this trailer shows the film has got mood to spare. The story follows investigator Bernie Kominski, who is suffering from insomnia and an impending divorce, who looks into the case of a man found bludgeoned to death in a London apartment block. But the enigmatic and beautiful Anna Welles distracts him from his work. They strike up a relationship, and though Anna declares she’s never met him before, she has a dark secret that will soon be revealed.

“I, Anna” will hit the Locarno Film Festival in August, before opening in the U.K. on October 12th. No stateside date at the moment, but we’ll see if it crosses the pond. Watch below.
